    摘要： A cluster or array of reference electrode materials is prepared and used to monitor the state of charge of positive and negative active electrode materials of a lithium-ion cell. The reference electrode materials are composed so as to provide useful electrochemical potential values when placed in the same electrolyte in proximity with a positive or negative electrode. The array of reference electrodes includes at least two electrically discrete instances of reference electrode materials. Such duplication of reference material in the array permits confirmation of the present quality and activity of a reference material used for evaluation of positive and/or negative electrode material in a lithium-ion cell.

    摘要： An electrified powertrain for a vehicle includes a battery system configured to switch individual battery modules between series, parallel, and bypassed connections, thereby eliminating the need for a DC-DC converter. The battery system is also configured to generate (via a set of drive switches) AC voltages for an electric motor, thereby eliminating the need for an inverter. Control methods for the electrified powertrain, which could be implemented in a controller of the vehicle, include controlling the switches of the battery system to maintain a constant desired output voltage during both discharging and recharging. The control methods also include controlling the series, parallel, and/or bypass switches of the battery system to bypass malfunctioning battery modules and/or to decrease the output voltage of the battery system below a voltage threshold that requires electrical isolation.
